When I was getting ready for bed, I took a moment to look out the window of my apartment. Upon noticing the clear sky, I saw what appeared to be a small craft, like an airplane or satellite, traveling from north to south at a slow pace. As I studied it, I thought it might have been an aircraft coming to or from Paine field, which is a ½ mile away. Then a second later, the craft sped up with extreme, high velocity across the sky and suddenly turned into a bright, yellowish fireball-orb. It raced across the sky with great speed and made a quick zigzag motion before flying out across the southeast direction of the horizon. I have seen plenty of shooting stars in my lifetime, but this was no shooting star.
